PIN.

Specification of Letters Patent.

Patented June 21, 1910.

To all whom it may concern:

Be it known that I, CHARLES KUEHNER, a citizen of the United States, residing at Cranston, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Pins, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to pins, and has for its object to provide simple, inexpensive and effective means whereby the catch and joint members of the pin may be formed integral with the back plate.

In carrying out my invention the pintongue retaining member is formed by bending outward a portion of the back plate which renders the joint very strong and durable. The stem of the pin is then passed through an elongated hole in one of the walls of said member, the upper edge of said hole being for the purpose of limiting the upward motion of the pin tongue while the lower edge of the hole forms a fulcrum against which the pin-tongue rests in order to produce suflicient tension to hold the point in the catch member. By this means the pin is firmly supported in the joint and by being limited in its backward motion is more readily passed through the fabric or other material when being applied by the wearer.

Another feature of my invention is that the catch member is elongated on one side so as to extend over and cover the point of the pin-tongue when the same is bent down and retained in the catch.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claim.

In the accompanying drawings: Figure 1is a perspective view showing the underside of the pin with the pin-tongue released from the catch member. Fig. 2is an enlarged blank illustrating the shape in which the same is cut from the stock. Fig. 3is

a side elevation of the plate showing the pintongue retainin member bent inward in a U-shape loop. ig. -is a side elevation of said plate showing the in-tongue retained in position in its retaining member. Fig. 5is a sectional view of the plate showing the point of the pin tongue bent around to engage the catch member, said catch member being of a length sufiicient to inclose and cover the point of the pin-tongue. Fig. 6is a greatly enlarged detail illustrating the method of forming the pintongue retaining member'integral with the back plate. Fig. 7is an enlarged view of the pin-tongue having a T-shaped head.

Referring to the drawings 1 designates the front portion of the pin and 2 the back plate thereof over which latter the edge of the former plate may be rolled to secure the two together. This back plate is preferably blanked out of sheet stock and formed a little longer than the body of the front shell into which it is to fit, the catch member 3 is formed integral with said plate near one end thereof. This catch member is formed with a forwardly projecting lip 4 for the purpose of extending over the point of the pin stem to entirely cover and protect said point when held within said catch. The stock forming the back plate is cut out adjacent the other end to form a narrowed portion 2 which is provided with an elongated hole 5 for the purpose of receiving the stem of the pin-tongue. The narrowed portion 2 is then bent or forced outward from the plane of the plate into substantially a U-shaped loop, as illustrated at 6, see Fig. 3, the pin stem hole 5 being in one of the walls of the loop and in position to receive the pin stem therethrough. The end of the back plate adjacent said loop is extended for a slight distance beyond the loop and is disposed to lie in the same .plane as the major portion of the back whereby the extended end of the back plate serves to hold the walls of the loop together under that stress which would otherwise tend to separate them. Since the front plate 1, has its edges rolled over the back plate 2 and the said extended end of the same, it firmly supports the loop; and the fulcrum wall of the loop, which is that wall in which hole 5, is formed, is thus held in its .related position to the opposite wall forming the loop, against any spreading tendency, which latter exists when the pin tongue is moved to engage the fulcrum wall in entering the catch member.

The pin tongue 7 used in the joint member is preferably of the type having a T- shaped head 8 and when placed in position with the stem extending through the hole 5 plate,

said head will lie in the bottom of the U-, shaped member. The walls of the stock 9 above this head are then drawn or "forced together thereby forming a strong joint member integral with the back plate, the forming of which member from the stock of the vplate naturally shortens up said plate to the required distance to exactly lit into the front cup member as shown in Fig. 1. I: In assembling the front and back plates '1' and 2, it will-be noted thatrby reason of the narrowed portion 5.2 the edge of the front plate :may be rolled over :the edge of the back ;plate in a --continuous unbroken flange, which -couldvnot-be done if the metal forming loop 6 was as wide as the :remaining portion of plate 2.

An essential :fea'ture of my improved pin is :that owing to the slotted hole through the wall ofithe joint member the backward swing of the pin-tongue is limited, that is, the tongue is allowed to swing back against the outer edge of the slot to that angle from the body which is tou-nd in practice to be imostadvantageous in applying the :pin to the goods by the wearer. The pin stem :is then carried toward the body portion and brings up against the inner edge of the slot which thus formsa fulcrum for the purpose of producing a tension. sufficient to cause the spring *of the .pin to firmly hold thepoi-nt in the catch member.

The device is very simple andinexpensive, also strong and durable in construction and by its use the attaching o'fth'epin is greatly facilitated.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

A pin comprising a back plate provided with a portion adjacent one end bent to form a loop, the said end of said'plate be- 7 ing extended for a distance ibeyond said lioopand being disposed :to .i'lie in the same plane as "the major Lportion or said back plate, said loop having one of its walls formed with :an opening, a pin tongue having a FT-shaped "head, the head being pivoted in the E1001) and the tongue proper extending through said wall opening of the loop and being fulcrumed on said wall of the loop having said opening, and a front plate rolled over the 'edges of theback plate, whereby said extended end of the back plate is held to :firmly support the loop-and prevent same from spreading when the pin tongueis moved .to engage the fulcrum wall of the loop vinrentering the catch member.

Intestimon-y whereof I affix my signature in ipresence :of two witnesses.
